The present invention is an extruded packaged pet food product for use in the health of pet animals, with more than 15% to 30% water, 11% to 45% carbohydrates, fats and proteins, and more than 0.7. For extruded pet food products with Aw. The present invention is a method of health in animals, having a water content of> 15% to 30%, carbohydrates of 11% to 45%, Aw of> 0.9, and densities in the range of 250 to 300 g / l. It also relates to a method comprising the process of feeding extruded packaged pet food products to pet animals.

There is a general need in the art to provide pet food products for use in the health of pet animals.

The present invention addresses this. Further, the product of the present invention is a natural product. This is because no additional ingredients are used to produce the effect achieved and there is no negative association with known solutions.

Accordingly, the present invention, in the first embodiment, is an extruded packaged pet food product for use in the health of pet animals, with more than 15% to 30% moisture, 11% to 45% carbohydrates. Provided are extruded pet food products with fats and proteins, Aw> 0.7, and densities in the range 250-300 g / l.

Extruded products may have no components applied after extrusion. In the prior art, extruded foods are usually coated with fats such as chicken, pork, lard, copra oil after drying to increase the taste and energy supply. Extruded pet foods are also known to be coated with liquid flavors such as digests; solid flavors such as powder and, in some cases, thermosensitive nutrients, for example, by coating the pet food with green mussels. It is applied to extruded and dried pet food. The present invention avoids any negative effects of applying certain ingredients after extrusion of pet food, and in detail, the health benefits are discussed in detail below.

The product may have a moisture content of 20% to 27%. The product may have a moisture content of 15% to 20%. The product may have about 18% moisture. The product may have 13% to 17% carbohydrates.

It is preferred that the pet food product is intended for use in achieving good health in domestic dogs or domestic cats.

The product may be produced, at least in part, in the presence of superheated steam. The Aw of the product may be greater than 0.9 or greater than 0.92. The Aw of the product can be greater than 0.8.

The product may further contain an acid, preferably the acid being lactic acid. The acid may be present in an amount of 0.5 to 10%.

The food is packaged. The packaging may be any, and a sealed package is preferable. The packaging material may be paper, cardboard, plastic or metal flakes, and / or cans, screw cap bottles or film pouch packs. The packaging may be sealed. One of the packaging may be vacuum packaging. The food may be packaged under sterile conditions (eg, in the presence of superheated steam) or processed to achieve sterile conditions (eg, by X-ray irradiation).

A second aspect of the invention is a method of health in animals, with more than 15% to 30% water, 11% to 45% carbohydrates, more than 0.9 Aw, and 250 to 300 g / l. Provided is a method comprising feeding a pet animal an extruded packaged pet food product having a range of densities.

The extruded packaged pet food product according to the second aspect of the present invention may be produced, at least in part, in the presence of superheated steam.

All the features of the first aspect of the present invention also apply to the second aspect.

INDUSTRIAL APPLICABILITY According to the present invention, a semi-moist pet food product having the moisture level described in the claims can be produced and maintained in a package to achieve a long shelf life. One way to obtain such extruded pet food products would be by the use of superheated steam. Any process that uses superheated steam may be used to produce the products according to the invention.

The pet food product is in any of the formats described in the claims and specification. The pet food product may also be described as a kibble, snack, treat or biscuit. The texture of the product is soft. The soft texture will promote chewing and thus increase meal time, thus contributing to the satiety effect. This soft texture is unexpectedly obtained in the absence of water binders such as glycerol (used to ensure shelf life stability). The ability to obtain such soft textures contributes to the satiety effect obtained in combination with specific moisture levels and Aw to provide products that can be stored for long periods of time at room temperature. Kibble's water content and texture require longer chewing times that will contribute to the satiety effect.

It is preferable that the pet food product is a commercially available pet food product. It is preferred that such products be sold as products for feeding cats or dogs.

The pet food product of the present invention has the following uses (one or more) in the health of pet animals:
• Oral hygiene benefits (by increasing oral food processing); reducing plaque in the mouth;
Gastrointestinal (will not contain additional ingredients after formulation, extrusion);
Dermatology (less allergens, will not contain additional ingredients after extrusion);
・ Mobility (weight loss / management);
-Kidney (less phosphorus, will not contain additional ingredients after extrusion).

The present invention avoids any negative effects of using standard coatings after extrusion of pet food, thereby resulting in the improvement of animal health as described above. Standard coatings applied after extrusion usually contain high levels of fat. Since the present invention avoids the addition of post-extrusion components, the pet foods of the claims contribute to a reduction in pet fat intake, which in turn contributes to dyslipidemia, pancreatitis, and exocrine pancreatic secretions. It results in reduced or treated dysfunction.

Dyslipidemia is a disorder of lipid metabolism that results in an increase in blood lipids, especially triglycerides and / or cholesterol. Dyslipidemia that occurs after a meal is a normal physiological phenomenon, whereas dyslipidemia in a fasting state is an abnormal laboratory finding. While the predominant cause of dyslipidemia in dogs and cats is either hereditary or familial, secondary dyslipidemia is endocrine dysfunction (ie, diabetes mellitus, hypothyroidism, canine hyperadrenolysis). ) Or related to pancreatitis. The most common clinical signs associated with dyslipidemia include vomiting, diarrhea and abdominal discomfort. Dyslipidemia secondary to the underlying metabolic disorder is generally ameliorated by treatment of the primary disorder. Dietary fat restriction is the basis of treatment for hypertriglyceridemia. This is because chylomicrons (lipoprotein transport lipids) are produced from dietary fat origin. Low-fat diets such as those of the present invention have been shown to improve the lipoprotein profile of miniature schnauzers with primary dyslipidemia (Xenoulis PG et al, Journal of Veterinary Internal Medicine 2011; 25: 687 and Xenoulis PG et al, ACVIM Forum Abstract, 2013). Another study (Jeusette IC et al., Am J Vet Res, 2005, 66, 81-6) showed that plasma triglycerides and cholesterol in obese dogs fed a low-fat diet returned to normal.

Pancreatitis is an inflammatory infiltration of the pancreas. Acute pancreatitis is an inflammation of the pancreas that is not associated with permanent changes, whereas the chronic form is associated with pancreatic fibrosis and atrophy. However, chronic pancreatitis is less often associated with local and systemic complications and is usually a milder course of disease.

Risk factors in dogs include heredity, dyslipidemia, drugs, trauma and ischemia. Nutrition-related risk factors include obesity and a high-fat / low-protein diet (Hess et al., J Am Vet Med Assoc, 1999, 214, 46-51; and Lem et al., J Am Vet Med Assoc. , 2008, 233 1425-31).

Pancreatitis is generally thought to occur when digestive enzymes are prematurely activated in the pancreas. Experimental pancreatitis can be caused by overstimulation of CCK (cholecystokinin) analogs. CCK is normally released by cells in the duodenum in response to intracavitary fats and amino acids. This gastrointestinal hormone regulates and stimulates pancreatic secretion and gallbladder contraction during digestion.

Fat restriction is generally recommended in long-term nutritional management of patients with pancreatitis to limit pancreatic irritation due to CCK release (Villaverde C, Applied Veterinary Clinical Nutrition, Fascetti, A J and Delaney SJ (eds), 2012). Again, the pet food products described in the present invention can be used to reduce fat intake, thereby treating pancreatitis.

Exocrine pancreatic insufficiency (EPI) results from a severe loss of pancreatic function. The pancreas is unable to provide sufficient digestive enzymes, bicarbonates, and other substances for proper digestion and absorption. This results in poor assimilation of fats, carbohydrates and proteins. The main clinical signs observed are chronic diarrhea, weight loss, and polyphagia (Westermarck E and Wiberg M, Vet Clin North Am Small Anim Pract, 2003, 33, 1165-79, viii-ix). Enzyme supplementation is the go-to tool for the treatment of patients with EPI. However, lipase activity never reaches levels comparable to healthy animals due to acid and protease destruction in the stomach, and many treated patients still suffer from some degree of steatorrhea. Lipase is a limiting step in fat digestion, considered to be the most difficult nutrient to digest and absorb, so feeding a highly digestible low-fat diet is a strategy to limit fat malabsorption. Has been proposed. A study of EPI dogs showed weight gain after treatment with pancreatic enzymes and a low-fat diet (Simpson J W et al., J Small Anim Pract, 1994, 35, 133-138). It is possible to treat an animal suffering from EPI by supplying a prescribed diet containing the pet food product of the present invention. This is because the diet is a low-fat alternative to currently available pet foods.

Another direct benefit from reduced total fat intake by animals fed the pet food products of the present invention is increased mobility due to weight loss. Obesity is a major risk factor for orthopedic disease in companion animals, especially dogs. This is mainly due to excessive weight load on the joints and bones that exacerbate orthopedic disease. Several studies have highlighted a link between obesity and the development of osteoarthritis (Kealy RD et al., J Am Vet Med Assoc, 1997, 210, 222-5; and Kealy RD et al. , J Am Vet Med Assoc, 2000, 217, 1678-80), while weight loss can result in a significant improvement in the degree of difficulty walking in dogs with osteoarthritis of the hip joint (lmpellizeri JA et. al., J Am Vet Med Assoc, 2000, 216, 1089-91).

Another study (Marshall W Get al., Vet Res Commun, 2010, 34, 241-53) undertook a 16-week weight loss program with clinical and roentgenological signs of osteoarthritis 14 The effect of weight loss on dogs was evaluated. The results show that weight loss significantly reduced walking difficulties with a 6% weight loss. This confirms that weight loss should be raised as an important treatment for pets with osteoarthritis.

Diets that reduce energy intake remain the most successful method for managing obesity in dogs and cats. Feeding animals with a low energy density prescription diet helps reduce their daily caloric intake for successful weight loss (German A Jet al., Res Vet Sci, 2009, 87, 249-54; German). A Jet al., Vet J, 2010, 183, 294-7; Yamka RM et al., Intern J Appl Res Vet Med, 2007, 5, 125-132; German A Jet al., J Feline Med Surg, 2008, 10, 452-9; Hoenig Met al., Am J Physiol Regul lntegr Comp Physiol, 2007, 292, R227-34; Bissot T et al., J Feline Med Surg, 2010, 12, 104-12).

Reducing the fat content of a regular diet reduces the energy density of the food. Fat has more than twice as many calories per gram as protein and carbohydrates. As a result, limiting fat in a weight-loss diet reduces caloric density, which helps reduce caloric intake.

Considering that coatings applied after extrusion generally contain high levels of fat, extruded pet food products with no post-extruded ingredients contribute to the reduction of the total fat content of pet food and osteoarthritis. It will benefit obese pets, including those with illness.

Feeding pet food without any additives after the extrusion process can provide other medical advantages such as reduced harmful food reactions on the skin and benefits of the kidneys.

Hazardous skin food reactions (CAFR), or food-induced atopic dermatitis, are pruritic and inflammatory skin disorders that result from oral ingestion of the causative allergen. Food allergens are basically proteins or glycoproteins ranging from 10 to 70 kd (Hefle SL, Food Technology, 1996, 50, 86-92).

The walls of the gastrointestinal tract are the largest body surfaces exposed to the environment and therefore exogenous antigens. The digestive mucosa is a specific immune system that allows the mucosa to react to pathogens (bacteria, viruses, parasites), while the process of oral resistance (acquired during infancy) is usually its resistance. Prevents the virus from reacting to dietary proteins. Disadvantages in this process will help develop allergies.

Therefore, CAFR occurs for allergens to which an animal is exposed (meaning proteins previously fed by the animal). In dogs and cats, these allergens are primarily of animal origin, but they can also be of grain origin (Verlinden A et al., Crit Rev Food Sci Nutr, 2006, 46, 259- 73; Roudebush P et al., Small Animal Clinical Nutrition, 2010, 5th ed Topeka: Mark Morris Institute; Roudebush P, Vet Dermatol, 2013, Letter to the Editor; and Fiora P et al., A retrospective study on the prevelance and causative allergens of food-induced atopic dermatitis in France, Short Communication at ESVD Congress, 2013, Valencia).

Treatment of CAFR is primarily diet. Because the treatment is a selected protein diet (a protein source that the pet has never been exposed to) or a hydrolyzed protein diet (natural proteins are hydrolyzed into small peptides that the immune system does not recognize). This consists of avoiding harmful food allergens by using one of the following (Verlinden A et al., Crit Rev Food Sci Nutr, 2006, 46, 259-73).

The flavors used in dry pet food consist of animal proteins, which are generally hydrolyzed, but the level of hydrolysis is not high enough and can still produce peptides recognized by the immune system. Yes, it may cause CAFR. Therefore, the risk of CAFR will be reduced if flavoring is not used in extruded pet foods such as those described in the present invention.

Chronic kidney disease (CKD) results from an irreversible loss of renal metabolic, endocrine and excretory capacity. CKD is a common clinical problem estimated to affect 2-6% of all dogs and cats diagnosed with veterinary medicine (Lund EM et al., J Am Vet Med Assoc, 1999, 214). , 1336-41 and Bronson RT, Am J Vet Res, 1982 43, 2057-9). CKD is considered to be the leading cause of death in aged animals. The diet is considered to be the basis for the management of chronic kidney disease with the aim of altering disease progression, controlling the symptoms of uremia, and ultimately improving quality of life. Phosphate retention is one of the most common dysregulations of CKD secondary to phosphorus-reduced glomerular filtration. Hyperphosphatemia occurs early in CKD and is the development of renal secondary hyperparathyroidism, renal bone dystrophy, relative or absolute deficiency of 1,25-dihydroxyvitamin D, and soft tissue calcification. And play an important role in progress. High plasma phosphate levels have also been associated with shorter survival times in cats with CKD (Boyd L Met al., J Vet Intern Med, 2008, 22, 1111-7; and King J Net al., J Vet. Intern Med, 2007, 21, 906-16). Initial minimization of hyperphosphatemia can prevent secondary hyperparathyroidism and its sequelae (Finch NC et al., J Am Vet Med Assoc, 2012, 241, 1326-35). ..

Dietary phosphate restrictions include dogs (Brown SA and Finco DR, Am J Vet Res, 1992, 53, 569-73; and Finco DR et al., Am J Vet Res, 1992, 53, 2264-71) and cats ( Barber PJ et al., J Small Anim Prac, 1999, 40, 62-70) has been shown to slow the progression of renal failure, reduce plasma parathyroid hormone, and reduce renal petrification and fibrosis. (Ross LA et al., Am J Vet Res, 1982, 43, 1023-6). Dietary phosphorus restriction was associated with increased survival time in cats with CKD (Elliott J et al., J Small Anim Pract, 2000, 41, 235-42).

Given that the coatings applied after extrusion generally contain high levels of phosphorus, extruded pet food products without post-extrusion components, such as those described in the claims of the invention, are pet food total phosphorus. Will contribute to reducing the content. Such a process would allow for dietary phosphorus restriction that would treat pets with chronic kidney disease.

A typical pet food of the present invention contains about 20-30% crude protein and about 10-20% fat, the rest being dietary fiber and carbohydrates containing ash.

The remaining ingredients of the pet food are not essential to the present invention and can include typical standard ingredients. The mixed ingredients of pet food according to the invention can provide all of the vitamins and minerals recommended for the particular animal in question (a perfectly balanced food).

The pet food is preferably a cooked product cooked during extrusion. The product may contain meat or animal-derived material (beef, chicken, turkey meat, lamb meat, fish, plasma, bone marrow, etc., or one or more of them). Alternatively, the product may be meat-free (preferably containing meat substitutes such as soybeans, corn gluten or soy products) to provide a protein source. The food may contain additional sources of protein such as soy protein concentrate, milk protein, gluten and the like. The food may also contain starch sources such as one or more grains (eg, wheat, corn, rice, oats, barley, etc.). It is preferred that the product contains at least one fiber source.

Manufacturing products using superheated steam is common knowledge in the art. Such methods are well known and have previously been published in International Publication Nos. 2009/018990, 2009/018996, 2009/018997, 2010/11097, and 2010/108641. It is described in the literature of.

Products manufactured, at least in part, in the presence of superheated steam include one or more of the following:
The extruded product provides superheated steam to a gaseous atmosphere in a housing, supplies the product to a gaseous atmosphere, delivers the package to the gaseous atmosphere, fills the package in the package, and seals the package in the gaseous atmosphere. It is then packaged by moving the filled package out of the gaseous atmosphere. The temperature of the gaseous atmosphere may exceed 100 ° C, 120 ° C, 140 ° C, 160 ° C, 180 ° C or 220 ° C. The gaseous atmosphere may be atmospheric pressure, reduced pressure or increased pressure. The gaseous atmosphere may be a mixture of a first component consisting of air and / or another gas and water vapor as a second component, at least in the horizontal sublayer, at least 50% by weight, 60% by weight, 70%. It has a water vapor content of mass%, 80% by mass, 90% by mass, 95% by mass, 98% by mass, and 99% by mass. The gaseous atmosphere in at least one horizontal sublayer may have an oxygen content of less than 15% by weight, 10% by weight, 8% by weight, 5% by weight, 2% by weight, or less than 1% by weight. The gaseous atmosphere may be layered vertically, with increasing temperature and decreasing oxygen content towards the top. The extruded product may be dried for a predetermined time prior to packaging by staying in a gaseous atmosphere. In the process, volatile substances that escape from the material, especially flavors, may be extracted from the gaseous atmosphere. The gaseous atmosphere present in the housing may be mixed to avoid vertical layering.

The present invention relates to a product in a packaging form in which food is cooked, dried and packaged in an atmosphere of superheated steam.

In the prior art, foods have typically been dried to an Aw value (active water content) of about 0.60 or 0.65. The reason for such desiccation is that higher Aw values have been understood to result in uncontrolled growth of any microorganism remaining in the food, such as bacteria, fungi, yeast. Lowering the pH can also be used to control the growth of sporulating bacteria. A pH reduction of less than 4.5 can be achieved by the addition of an acid such as lactic acid. The pH can be lowered by acidification of the dry mixture during the extrusion process.

Recent studies have shown that, under certain circumstances, substantially less thorough drying of moist products may be sufficient to obtain a packaged product with satisfactory long-term storage stability. When a food is dried in a superheated steam atmosphere containing less than 3% O ₂ at a temperature of at least 120 ° C. to an Aw value of at most 0.9 or 0.92, the food will have 3 volumes. No viable microorganisms can grow under the condition that they are hermetically sealed while in the atmosphere of superheated steam with an oxygen content of% or less.

The method of producing packaged food in the presence of superheated steam is the step of cooking the food at a cooking temperature of at least 100 ° C., the cooked food containing less than 3% oxygen and having a temperature of at least 120 ° C. It has a step of introducing the food into a steam atmosphere, a step of drying the food to an Aw value in the range of 0.7 to 0.92, and a step of packaging the food in a packaging container in the atmosphere of superheated steam. May become. The packaging may then be sealed.

The atmosphere of superheated steam during the process may be maintained at a temperature of at least 130 ° C. The food may be cooked in water, saturated or superheated steam, or a mixture thereof. The food may be cooked in an extruder and may be extruded directly into the atmosphere of superheated steam.

According to the superheating process, the food may be dried during a drying time of at least 20 seconds, 30 seconds, 40 seconds, 1 minute, 2 minutes, 5 minutes or 10 minutes. The food may be sterilized by drying for at least 5 minutes or at least 10 minutes.

Cooked and dried food may be packaged without the addition of any ingredients, including any preservatives. During the packaging process, the packaging container may have a protective gas supplied during the packaging.

The temperature of the food may be maintained above 100 ° C. between cooking the food and sealing the packaging container. The food may be cooked while being extruded. The atmosphere of superheated steam may be maintained at atmospheric pressure. The protective gas may be CO ₂ or N ₂ .

The process of manufacturing the product in the presence of superheated steam is a method of frying food, in which the food is delivered to hot oil or fat, carried out of the hot oil after a predetermined residence time, and ambient air. A method of creating a steam zone containing superheated steam on the free surface of the oil, which shuts off the oil from the oil and sucks out a stream of steam corresponding to the amount of water evaporating from the fried food. May include. The superheated steam may be circulated, in the process where the steam is extracted from the steam area, passed through a heat exchanger if necessary, and returned to the steam area by a blower. The water vapor may be sprayed onto or over the free surface. The volume of water vapor present or circulated within the water vapor area may remain constant. The oxygen content in the water vapor area above the oil may be maintained at 10% by volume, 5% by volume, 3% by volume, 2% by volume or less than 1% by volume. The stream of water vapor may be at least partially condensed, especially to heat the oil, and energy and / or material may be recovered. The present invention is a method of drying an extruded material in a superheated steam process, in which a step of providing superheated steam in a gas atmosphere in a housing, a step of extruding the material in the housing, and drying the material in a gas atmosphere. It may include a process and a method comprising the process of moving the dried material out of the housing. The temperature of the material may be higher than 100 ° C, 110 ° C, 120 ° C, 130 ° C or 140 ° C as it enters the housing. The temperature of the gaseous atmosphere may exceed 100 ° C, 120 ° C, 140 ° C, 160 ° C, 180 ° C or 220 ° C. The gaseous atmosphere may be a mixture of a first component consisting of air and / or another gas such as CO ₂ , nitrogen or another inert gas, and water vapor as the second component, at least 50 mass. It has a water vapor content of%, 60% by mass, 70% by mass, 80% by mass, 90% by mass, 95% by mass, 98% by mass, or 99% by mass.

Volatile substances that escape from the material into the gaseous atmosphere, especially flavors, may be extracted from the gaseous atmosphere. After extraction, the substance may be added back to the material. The material may be added directly to the material or in the form of a carrier material such as a coating or padding. The method in the presence of superheated steam is a method of drying the material, which is a step of providing superheated steam to a gaseous atmosphere in a housing, a step of bringing the material into the housing, and drying the material in a gaseous atmosphere. It may include a process of allowing, carrying the dried material out of the housing, and a step of extracting the volatiles, in particular the flavor, from the material into the gaseous atmosphere.

The present invention can be described with reference to the following non-limiting examples.

Objective The purpose of this trial was to evaluate the effectiveness of the extruded product according to the present invention. Comparisons are made between products containing the same ingredients manufactured by different techniques and having the formulations shown below.

Conditions The test pet food product of the present invention was manufactured using the following process:
Prerequisite settings included products with 29% moisture.

The product was extruded at a temperature of about 125 ° C. and a pressure of about 20 bar (2 MPa).

The product was extruded into an atmosphere of superheated steam at 120-140 ° C.

The product was a round die plate with dimensions of 13 mm and a thickness of 7 mm, and a round die plate with dimensions of 7.3 mm.

The process is illustrated in FIG.

Two protocol products were grade tested. Two products with the above formulation were used.

The design used for the test was a randomized crossover test. Each week, dogs were fed three of two prescribed diets (test or control) (dynamic). The following week, another study or control diet was used.

The test description is set as follows:

The result was that each dynamic had a total food intake represented by kcal / kg ^0.75 .

The test was performed on 10 adult Beagle dogs. These dogs were able to drink unlimited water.

Energy requirements are:
− 120 kcal / kg ^0.75 corresponds to 100% of the energy requirement,
-240 kcal / kg ^0.75 corresponds to 200% of the energy requirement.

The results also included the fact that no diarrhea or constipation was observed with respect to digestibility.

The ingredients of the product as described in the product manufacturer were mixed and extruded. For the test product, at least a part of the product was produced under superheated steam as described above. A control diet was dried and coated with a fat and umami agent specific to dried kibbles (poultry fat).

The result is shown in FIG.

FIG. 2 shows that the test diet is eaten 43% less than the control diet.

Another result is shown in FIG.

FIG. 3 shows that a satiety effect appears after the first meal (34% reduction in food intake).

Yet another result is shown in FIG.

FIG. 4 shows that satiety cannot be explained by a less tasty product, but can be explained by a combination of a low-energy prescription diet and a soft texture, which tends to increase the time between meals, due to the superior tasting of the product. Indicates that it will be confirmed.

Oral hygiene test Two product grade tests were performed on 7 Schnauzer dogs. Two weeks before the start of the study, dog tartar was removed and brushed. Dogs were fed a control diet for a period of 10 days and then a test product for a period of 10 days. For both regular diet periods, plaque deposits were brushed off before the first diet and monitored after the 10th diet (percentage of surface plaque).

Yet another result is shown in FIG.

FIG. 5 shows a reduction in plaque on the teeth of dogs fed the test pet food product relative to the control pet food product. The teeth of dogs fed the control diet show more plaque in the photo than those found on the teeth of dogs fed the test diet.

Yet another result is shown in FIG.

FIG. 6 shows a significant 17.2% reduction in plaque on day 10 in dogs fed the test pet food product relative to the control pet food product.

Yet another result is shown in FIG.

Figures 7A and 7B show that dogs fed the test pet food product took longer to consume the pet food (significant increase of 19.1%) than dogs fed the control pet food product, thereby. , Shows that chewing time increases and the amount of pet food formed on dog teeth decreases.

Yet another result is shown in FIG.

FIG. 8 shows the appearance of a test pet food product relative to a control pet food product.
